Be added with the water reducer of mole total amount 2 ~ 5% of inorganic gel slurries in described inorganic gel slurries, described water reducer is naphthalene water reducer or polycarboxylate water-reducer.
The organic adhesive that steps A 5 adopts is acrylic acid, or polyvinyl acetate, or nature rubber latex.
Described strip of paper used for sealing is wooden skin or metal skin.
Beneficial effect of the present invention is: owing to adopting above-mentioned production technology, especially have employed the inorganic gel slurries be made up of magnesium chloride, magnesia and water, and its concentration is controlled, not only make sheet material have light weight, anticorrosion, easy processing, feature that cost is low, but also add fireproof performance; Owing to the addition of appropriate water-soluble borate and acylate in inorganic bond, effectively can disperse the heat in hydration reaction, thus effectively control the setting time of inorganic adhesive, make inorganic adhesive in vegetable fibre board, have splendid permeability, decrease the heat deflection of vegetable fibre board simultaneously, enhance the density of texture of vegetable fibre board; Especially after with the addition of water-soluble borate and acylate, can reduce the addition of water in bonding agent, for processing high-quality, the Fireproof plant fiber furniture board of high strength lays a good foundation.
detailed description of the invention
embodiment one
The fibres fire prevention furniture-plates of the present embodiment, comprise vegetable fibre board and strip of paper used for sealing, described strip of paper used for sealing is fixed on the both sides of described vegetable fibre board; The preparation technology of described vegetable fibre board comprises the steps:
A, be that raw material makes slab by paving process with coconut fibre, the density of slab is 0.18g/cm3;
B, slab is immersed the mass percent concentration be made up of magnesium chloride, magnesia and water is soak in the inorganic gel slurries of 50%, and soak time is 5 ~ 10 minutes;
C, the slab after soaking is sent into roll-in in roller machine, after pressure, the density of plate is 0.8g/cm3;
D, by solid by maintenance for the plate of roll-in, cutting facing make vegetable fibre board.
Coco is aiphyllium, and coconut is the fruit of coco, and its skin by brown fibers encapsulation, and this brown fiber is exactly coconut fibre.The intensity of coconut fibre is far away higher than common plant filament, and abundance, environment protection health; In a collection of coconut fibre, there is different lengths, select the coconut fibre within the scope of length 5 ~ 30cm to have best result of use;
Coconut fibre needs the slab making the basis as various post processing through paving process, this slab be by the coconut fibre being piled into mountain through breaing up, combing, lapping, acupuncture, glue spraying, drying and hot pressing technique finally formed.After paving process, coconut fibre is formed to square-folded sheet material independent one by one, piles up for subsequent use.
Because furniture will load a lot of article, and durable in use, and therefore as the vegetable fibre board of Fireproof plant fiber furniture board, must have higher intensity, so should have larger density, 0.18 ~ 0.20g/cm3 is the most rational density.
Paving process in described steps A comprises step:
A1 breaks up: broken up by coconut fibre; The coconut fibre of acquired original is piled into mountain, coconut fibre is broken up the coconut fibre forming the sheet be laid on the conveyer belt of spreading machine;
A2 combing: the coconut fibre after breaing up is carried out combing, eliminates and is entangled with winding; Described carding equipment is cylinder, and the cylinder face of described cylinder is provided with the pin stretched out perpendicular to described cylinder face, and cylinder drives described pin that coconut fibre is carried out combing in rotation process; This process is similar to people and uses comb combing hair, is made in order by the coconut fibre of being entangled with winding, facilitates the process of next process;
A3 lapping: coconut fibre uniform throughout is tiled; No longer mutually be wound around by the coconut fibre after combing, be easily separated from each other tiling, coconut fibre is paved with whole conveyer belt by this step, and guarantees that coconut fibre thickness is even, in order to avoid affect the quality of final slab as far as possible everywhere;
A4 acupuncture: vertically move back and forth interspersed with several prickers by the coconut fibre after tiling, makes the levels of coconut fibre interlock and links; Described pricker is the barbed pin of end strips; In pricker inserting process, pricker makes the coconut fibre being positioned at levels different layers act in collusion, and coconut fibre is not misplaced up and down, plays the effect of preliminary sizing;
A5 glue spraying: organic adhesive is evenly sprayed at coconut fibre, makes coconut fibre shape; Described organic adhesive is acrylic acid, or polyvinyl acetate, or nature rubber latex.
A6 is dry: carry out drying to coconut fibre, dried coconut fibre begins to take shape tabular, and coconut fibre is now continuous print plate in blocks, and rolling is deposited for subsequent use;
A7 hot pressing: the coconut fibre after steps A 6 being processed cuts into suitable size, then the coconut fibre through A1-A6 step of multilayer formed objects is superimposed together, hot-forming slab.
In described step C, the pressure of pressure roller is 3200N/cm.
The length of described coconut fibre is 5 ~ 30cm.
Magnesium chloride in described inorganic gel slurries and magnesian weight ratio are 2:1.
Water-soluble borate and the acylate of mole total amount 1 ~ 3% of inorganic gel slurries is added with in described inorganic gel slurries.
The weight proportion of described water-soluble borate and acylate is 1:1.
Be added with the water reducer of mole total amount 2 ~ 5% of inorganic gel slurries in described inorganic gel slurries, described water reducer is naphthalene water reducer or polycarboxylate water-reducer.
The organic adhesive that steps A 5 adopts is acrylic acid, or polyvinyl acetate, or nature rubber latex.
Described strip of paper used for sealing is wooden skin or metal skin.Furniture surface adopts wooden skin or metal skin to have more modern house style.
Magnesium chloride and magnesia are fire-proof cement materials, because inorganic gel slurries adopt the inorganic adhesive being primary raw material with magnesium chloride and magnesia, can play good flame retardant effect to string; Because inorganic gel slurries with the addition of appropriate water-soluble borate and acylate, effectively can disperse the heat in hydration reaction, thus effectively control the setting time of inorganic adhesive, make inorganic gel slurries in vegetable fibre board, have splendid permeability, decrease the heat deflection of vegetable fibre board simultaneously, enhance the density of texture of vegetable fibre board; Especially after with the addition of water-soluble borate and acylate, can reduce the addition of water in bonding agent, for processing high-quality, the vegetable fibre board of high strength lays a good foundation; Owing to adding water reducer, thus the diminishing addition of water, and can ensure permeability and the mobility of inorganic adhesive.
